TELEPHONE ATTACHMENT.

Applicationfiled May 19,

users ear when he is talking into the transmitter or in a position whereit is out of the way when the telephone is not in use.

The primary object of the invention is the provision of an attachment ofthe foregoing nature incorporating mechanism for depressing the receiverhook when the receiver is moved from operative to inoperative positionand permitting the hook to rise uponmoving the receiver-to operativeposition.

Further objects are the provision of a comparatively simple device ofthe afore said characterthat'may be readily attached to telephones ofstandard design; is very convenient of use; positive of action; notlikely to get out of order; and easily and quickly adjustable to alterthe relation of receiver and transmitterto fit the requirements ofdifferent individuals.

I attain the foregoing objects, and others which will become apparent asthis description proceeds, in the attachment illustrated in theaccompanying drawings wherein Fig. 1 is a side elevation of a telephoneequipped with my improved receiver supporting attachment; Fig. 2 is afragmentary side elevation showing the receiverin operative position;Fig. 3 is a front elevation ofthe parts shown in Fig. 2; Fig. 4 is aplan view with the receiver omitted and a part of its supporting armbroken away; Fig. 5 is a detail illustrating the nature of the pivotalconnection between the receiver supporting arm and bracket; and Fig. 6is a sectional detail on the lines 66 of Figs. 1 and 4.

The telephone in connection with which my attachment is hereinillustrated is of the stand type and comprises a base 1, stem 2, andtransmitter 3. The receiver supporting hook 4 extends laterally from theupper end of the stem 2, and, in accordance with prevailing practice, isso connected to the Specification of Letters Patent.

switch of the talking circuit as to cause said circuit to be establishedwhen the hook is raised by its actuating spring and broken when the hookis depressed.

My attachment includes a supporting plate 10 secured to the telephone,in the present instance by being provided with a semicircularportion 10which passes about one side of the stem 2, and a correspondingly shapedclip 11 that is engaged about the opposite side of the stem and has itsends connected to the adjacent ends of the portion 10"-, by screws 12. Abracket 14 is pivotally connected to the upper end of the supportingplate 10, as by means of a bolt 15 (see Fig. 6) thatextends through therespective bosses 16 and 17 of the plate and bracket, a nut 18 beingapplied to the end of the bolt where it protrudes beyond the boss of theplate. v The bracket 14 may be adjusted about the bolt 15 to any angularposition with respect to the plate 10, and to securely hold it in anyadjusted position I employ a screw 20 which, in the present instance,extends through a segmental slot 21in the circular flange 22 of thebracket 14 and is threaded into the plate 10, the screw having a washer23 inserted between its head and the adjacent face of the flange. Byloosening the screw the bracket 14 may be swung to desired positionwhere it may be securely held by tightening the screw. The outer end ofthe bracket 14 is bifurcated and has pivoted to it, by means of a screw25, or the like, the inner end of the receiver supporting arm 26.referring to Fig. 5, the nature of this con nection prevents the armfrom swinging beyond approximate alignment with the bracket 14, thestraight end portion 27 of the arm engaging a part of the bracket. Theouter end of the receiver supporting arm is equipped with a clampportion 28 which cooperates with a clip 29 to hold, through theinstrumentality of the screws 30, the receiver 31.

35 is a finger that is pivoted upon the bolt 15 and extends out over thereceiver hook. A link 36 has one of its ends pivotally connected at 37to a part of the receiver supporting arm 26 near its inner or pivotedend, the link being spaced or oil-set from the arm to preventinterference with the end of the bracket 14, or the head of the screw25. At its lower end, the link 36 is slotted to receive a stud 38 whichextends As will be seen upon laterally from the finger 35.

For convenience in assembling the slot, which is designated 39, opensthrough the end of the link 36 although, after the parts are assembledthe ends on each side of the slot are pinched together somewhat toprevent the with drawali of" the stud from the slot.

In setting up the attachment, the supporting plate 10 may be clamped tothe stem 2 of the telephone in such a position as to cause the receiverto be properly disposed laterally with respect to the transmitter, andthe bracket 1. L may then be adjusted with respect to the supportingplate to bring the receiverto its proper elevation, after which thescrew 20 is tightened to securely hold the parts in such position. lViththe receiver thrown backward as shown in Fig. 1, it throws downward thelinger 35, through the intervention of the link 36, to depress thereceiver hook and break the talking circuit. IVhen it is desirable touse the telephone, the receiver is swung forwardly into the positionshown in Figs. 2 and 3 and by the swinging of the receiver sup portingarm 26, the link 36 is drawn upward to elevate the finger 35 and permitthe receiver hook 4 to rise, thereby to establish the talking circuit.

1 I have shown a brace 40, clamped to the stemv 2 immediately above thebase 1, the same comprising legs 41 which flare outward beyond the baseand bear upon the supporting surface to prevent oventilting of the phoneby reason of the added weight of, the attachment to its upper end.

Having thus described my invention, what I claim is:-

1. In a telephone attachment of the characterset forth, the combinationof a bracket secured to the telephone, a receiver supporting arm pivotedto the bracket, and adapted to be swung in a vertical plane from aposition forward of-the telephone to a position rearwardly thereof, afinger extending across the receiver hook and pivotally sup ported tothe rear thereof, and a link directly connecting parts of the receiversupporting armand the aforesaid finger adjacent their pivots.

2. In a telephone attachment of the character set forth, the combinationof a supporting. member secured to the stem of the telephone, a. bracketadjustably connected thereto, a receiver supporting arm pivotallyconnected to the bracket and adapted to be swung through a verticalplane, a finger pivoted to the supporting member and located inoperative relation to the receiver,

hook, and connections between the finger and receiver supporting armwhereby said finger is depressed when; the receiver supporting arm isswung from operative to inoperative position.

3. In a; telephone attachment of the character set forth, thecombination of a supporting member secured to the telephone, a

bracket pivoted thereto, means for securing said bracket to thesupporting member in any desired position, a receiver supporting armpivoted to the bracket, a, finger pivoted to the supporting member anddisposed in operative relation to the receiver hook, and a link directlyconnecting parts of the finger and the receiver supporting hook wherebythe swinging of the arm through a vertical plane fromoperative toinoperative position a will depress the finger. I

In testimony whereof, I hereunto aflix my signature.
